This invention lift pumps. y y

VyThe' primary object of this rinvention is the provision'of improvements in lifty pumps by means of which aj suction typeof pump:

maybey used for pumping water ro'mpcisterns, in such manner as to agitate the water inthe cistern and supply air thereto, positively,`during pumping operation, thus- 10 purifying the]y wate'rand keeping the 'same from getting stagnant, such asv would ordinarily occur with a lift or force pump.r

Q It is lof vcourse quite `apparent that 'upon oscillation' of the handle 30 the ypump rodQQO wil be recipro` cated, for lilewise'reciprocating the piston( 15 and drawing water upwardly intothe cyl-- inder` 14, from whence it is discharged past the check valve of thefpl'ungergl into the` compartment of the' reservoirjhead 1 3, from whence it vflows through an ordinary spout.`

The purifier kattachn'cent C is adaptedl lto be. attached to" existing types of pumps, such Y as that shown in Figuresl and 2 ofthe draw# ings, and above described. 'It consists of an air pumping cylindenZa, having upper and rotA p lower detachable caps 26"L and 27a, connected by means 27 to the reservoir head 18, or to other parts of t-he pump stock or casing, so as not to interfere with the withdrawal of water. This air cylinder 25a may be attached by bands by lugs as shown, or in any other approved vertical and stable relation upon the pump casing. A short piston rod Y is reciprocably disposed in a leak-proof connection thru a stuffing box 41 in the cylinder head 26 of the air cylinder, and supports an ordinary plunger 44L of the flexible gasket type at the lower end thereof within the compartment of the cylinder 25a. At its upper end the piston rod 40 extends exteriorly of the air cylinder and is suitably connected by an adjust-ableY and detachable bracket arm 44 with theupper end of the main pump rod 20, by means of a suitable connection. 45. The

air cylinder 253, and preferably the cap 26a, is provided with anV air inlet opening 47,

througliwhich air enters the cylinder during the upstroke of the piston 44a, and the latter flexes 'to permit the air to pass the same to the lower portion of the vcylinder below the piston or plunger 44a. In the bottom cap 27@LV is an outlet and exit 48, to which a fitting 49 connects the purifier pipe 50, which extends vertically downward into the well or cistern A.V VIntermediate its ends the purifier pipe 50 is provided with an voffset 52 having a check valve 53 therein which permits lair to beV forced downwardly through the pipe 50 and Yprevents the passage of water upwardly into the purifier pipeV incident to suction. `At its lower end, preferably below the pump inlet pumpingof air into the wellproceedsxposi- 2K5,`the.puriiier pipe 50 is provided with a T-shaped distributing` head 55, of a tubular nature, thru which -air is forced from the purifier pipe 50, and exits at the ends of said pipe 55 in streams of air which bubble upwardlythrough the cistern at opposite sides of the pump barrel or casing which depends into the well, as shownV in Figure 1of the drawings. Y l

The operation of the attachment C in con-y nection with the pump B will be apparent. On each stroke of the plunger rod 20, incident to an operation of thefhandle 30, the air cylinder piston 44i will be reciprocated, and the tively as the water is pumped, up into the reservoir head and discharged. Thus, means is provided for ypositively forcing air `into the cistern in a novel relation to purify the water and prevent its getting stagnant. f

In the special pump shown in Figures 3, 4, and 5, the details of the pump comprise a cylinder 6()V detachably connected t0 they lower end of the reservoir head 61, which is mounted upon the pump casing or stock 62 in the usual relation. The working barrel 63 is connected to t-he lower endl of the cylinder in the usual relation, and at vthe juncture of these parts a check valve 64 is provided which permits water to be sucked upwardly into the check valve plunger V67 thereon, of the ordinary suction pump construction, well known in this art.

As a novel' feature of the special pump H, shown in Figure 3 of the drawings, the reservoir head 61 may be internally Vscrew threaded at 70, for detachably receiving therein the lower end of an air cylinder body 71; the upper end of which body 71 detachably receives a cap 72 having an air inlet and outlet duct 7 3 therein, by means of which air may enter the cylinder 71; A gasket piston 74 slidably operates in the cylinder body 71, and it is clamped in place'on the top of the pump rod section 66 by. means of an upper pump rod section 75, thru a detachable connection at the plunger 74, as shown in Figure 3. The air cylinder cap 7 2 is provided with a stuffing box 78 at the top thereof, upwardly thru which the pump rod slidably extends.

A handle 8OY is pivotally connected at 81 witha-connecting link 82, pivoted at 83 on the bracket 84 of the pump H, and at the opposite side o'f the `pivot 81 from the hand engaging portion the handle is pivotally connected at 87 withtheupper end of the pump rod section 75. It is readily apparent thatl oscillation of the handle 80 will causel a reciprocation of the pumprod and a corresponding reciprocation of both the air plunger or piston 74 and the water drawing check valve piston 67.

yA purifier pipe 90 has a connection 91 in an inlet opening in the lower end of the aircylinder 71, and the puriiie'r pipe 90 extends downwardly `into the well in the same relation as the purifier pipe 50 above described, and intermediate its ends it is provided with a check valve 92 in the cistern or well, to pre vent up flow. of water thru the line 90 upon the upstroke of the airplunger 74.

Reciprocation of the plunger rod sections 66 and 75 will cause a synchronous opera- -be such` as not to obstruct the nozzle 100, from .whichV the water Hows from the reservoir head 61.

Various changes in the shape, size, and arrangementof partsmaybe made to the forms of invention herein shown and described, Y
